LAMP-OPERATING MECHANISM.

Specification of Letters Patent.

Patented Dec. 7, 1920.

Application filed December 17, 1917. Serial-K0. 201,40s.

To all whom it may concern:

Be it known that I, KARL A. 1(ENDR1CK, a citizen of the United States, and residing at Detroit, State of Michigan, have invented a new and Improved Lamp-Operating Mechanism,

of which the following is a specification.

This invention relates to means for turning lamps of motor vehicles on horizontal and vertical axes so that the beams of light therefrom may be projected onto the roadway at any desired distance from the vehicle or may be projected toward either side of the line of movement of the vehicle as desired, and its simple and effective mechanism by means of which the lampsof a vehicle may be thus directed as desired through the agency of a single operating member which may be located most conveniently for the person driving the'vehicle.

This invention consists, in combination with the lamps of a motor vehicle which are universally mounted to turn on horizontal and vertical axes, of actuating means for turning said lamps on either or bothof said axes at will, and a single manually operated member for actuating sa1d lamp-turning means.

In the accompanying drawings, Figure 1 is a side elevation of and the mechanism for turning the lamp on a horizontal axis, and for turning the support. of the lamp on its vertical axis.

' Fig. 2 is a plan of a'pair of lamps and mech'-- p anism for turning them. Fig. 3 is a section of a connector. Fig. 4 is a plan of a lamp turned on its vertical axis out of its normal position. Fig. 5 is a front elevalamp and a vertical section ofits tubular support. Fig. 6 is a perspective of the operating mechanism of the lamp. Fig. 7 is a perspective of a segment secured to the lower end of the rod by means of which the lamp is turned. Fig. 8 is a ver-' tical section of the mechanism for operating the lamp. Fig. 9 is a plan of a lamp and of the rods connected thereto.

Similar reference charactersrefer to like parts throughout the several views. Each lamp shown in the drawings is any desired construction and is carried by means of a fork 2, but is revoluble on the support 3. This fork carries pivots 4 tion. of "a 5 around which are wound the springs 5 in the county of Wayne and v object is to produce a a lamp, its support turned as a unit.

the flexible connectors 29 and 30,

integral with each other, which connectors bracket 10 may be employed to connect the support 3tothe side bar 9 and a cap member 11 may be screwed on to the lower end of the tubular support 3. If desired, ball bearings may be mounted between the fork 2 and the tubular member 3, and betweenthe ca 11 andthe segment 7 in order to rev duce t e friction. A spring 12 on the stem 6 within the casing normally turns the lamp outward. i 1

Mounted on the instrument board 13 of the vehicle is a circular plate 14 into which the tubular shaft 15 is secured. Connected to this plate 14 is a bar 16 which carries lugs 17. A pin 18 is mounted in these lugs and on it is pivoted a lever 19 by means of which this mechanism is manually operated.

Slidable within the tubular shaft 15 is a rod 21,which is connected to the lever 19 by means of a short link 22. This rod is threaded "or grooved at its outer end and may be engaged by means of the sharp inner end of a pin 24 which is connected to the bell crank lever 25, mounted on a small 0st 26 carried by the plate 14. If the rod 21 is'to be moved in or out by means of the lever. 19, the bell crank 25 will be turned to withdraw the pin 24 and the lever 19 may i then be swung to move the rod 21 in or out.

If desired, the plate 14 and the hollow shaft 15 and everything connected thereto may be ted on the hollow shaft 28 on which are wound preferably Adjustably men 15 is a small spool pass through the tubes 31 and attach to the segments 7 on the lower ends of the stems. 6. By turning the shaft'2l and the spool 28 the connector 29 may be wound up and the connector 30 unwound to turn the lamps to the left,=or' the disk 14 may be turned in the opposite direction to turn the lamps to the right.

Flexible connectors are attached to the those skilled in the versal joint 37.

lamps 1, as shown in Fig. 1, and then extend down and back through the tubes 33 to a block 34 in which they are positively held by means of screws 35. This block is mounted onthe member 36 which is connected to the stem21 by means of a uni- When the stem 21 is drawn back by means of the lever 19, the connectors 32 will pull'down the rear portions of the lamps 1 against the tension of the springs 5 and cause the lamps to throw their beams of light upwardly. If the lever 19 is depressed the springs 5 cause the rays of light to be projected downwardly. The flexible connectors specified above may be cords, chains, wires or tapes of any desired materials.

These operating devices for the lamps are readily adjustable relative to the lever 19 by means of the set screw 38 which holds the drum 28 on the hollow shaft 15 and, by means of the set screws 35 which secures the connectors 32 in position within the block '4. The initial positions of the lamps may therefore readily be varied by releasing these set screws and swinging the lamps to the. desired positions before again securing the screws;

The curvatures and lengths of the pipes 30 and 33 will depend upon the type of motor vehicle upon which this mechanism is 1 and proportions of' the various parts may of course all be varied,

installed. The details to meet the different problems presented by the various types of motor vehicles on which these dirigible lamps are to be employed, by art Without departing from the spirit of my invention as set forth in the annexed claims, and I do not, therefore, wish to be limited except thereby.
